INNER SOLE.

srnorrrcnrron forming part of Letters Patent 1%. 621,198, dated March14, 189. Application filed February 18,1898. Serial Ne. 670,836. Nomodel.)

To aZZ whom, it away cancer-n:

Be it known that I,JOHN V. ALLEN, of Weymouth, in the county of Norfolkand State of Massachusetts, have invented certain new and usefulImprovements in Inner Soles, of which the following is a specification.

This invention relates to inner soles, and particularly those adaptedfor use in welted boots and shoes, one side of. the sole being out alongits margin to form a stitch-receiving channel or channels. Thechanneling of the sole reduces its thickness to a consider.- ableextent, leaving the sole undesirably limp and flabby at its marginalportion.

My invention has for its object to stiffen the channeled portion of thesole Without increasing its thickness; and to this end it consists in aninnersole having its channeled portion provided with pins extending fromthe margin of the soleinwardly across the channel or channels cuttherein, the pins being between the bottoms of the channels and thesents a view similar to Fig. 3, showing the sole after it has beenchanneled.

The same letters of reference indicate the same parts in all thefigures.

In carrying out my invention I insert in the edge of an inner sole a aseries of slender pins 1), which are preferably of steel or othersuitable metal and are of such diameter that they can be insertedbetween the channels I) b and the side of the sole opposite the sidefrom which the lips 19 formed by the channels, project. The length ofthe pins is such that they project across the channeled portion of thesole, and they are placed sufficiently close together to cause them tostiffen the chan-. neled portion and prevent bending or curling underthe ordinary pressure to which it is subjected.

I prefer to insert the pins 1) before the operation of channeling thesole, but do not limit myself in this particular.

The lips b b are usually formed from the flesh side of the sole, and thepins 12 are therefore inserted in close proximity to the 0pp0. site orgrain side of the sole. The grain-sur face of the sole is sufficientlydense and firm to enable it to guide the pins as they are being drivenand prevent them from beingdefiected through the surface of the sole inclosest proximity to them.

I claim '1. A channeled'inner sole provided with a series ofstiffening-pins inserted in its edge and extending across the channeledportion.

2. An inner sole havinga channel or channels formed in its flesh side,and a series of pins driven into the edge of the sole, between the fleshand grain sides, the pins being in close proximity to and parallel withthe grain side.

In testimony whereof I have affixed my signature in presence of twoWitnesses.

JOHN V. ALLEN.
